Correct answer: D — Oral lichen planus
Wickham striae are fine, white, lace-like (reticular) lines that are pathognomonic of lichen planus. Oral lichen planus most commonly affects the bilateral buccal mucosa and may present in reticular, erosive, atrophic, plaque-like, papular, or bullous forms. Reticular is the most common form. Erosive lichen planus requires monitoring due to a small risk of malignant transformation (approximately 1-2%).
